16512064 ÷ 921 
We want to figure out the number of times 16512064 can be divided by 921.

Step 1:
If we divide 1 by 921, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 921

Advancing to step 2:
16 divided by 921 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 921

Going ahead to step 3:
921 can be fit into 165 0 times, resulting in a remainder of 165.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 165 after subtracting 0 from 165.
Take the next digit (1) from the dividend and append it to 165, then repeat: 1651 / 921

Advancing to step 4:
921 goes into 1651 1 times with a remainder of 730.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 921 from 1651 and we're left with 730.
Bring next digit (2) of the dividend behind the 730 and repeat the process: 7302 / 921

Step 5:
7302 divided by 921 is 7 with a remainder of 855.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 6447 from 7302 leaves us with 855.
Fetch the next digit (0) from the dividend, attach it to 855 and continue: 8550 / 921

Advancing to step 6:
The number 921 fits into 8550 9 times, leaving a remainder of 261.
Put 9 as the next digit of the answer. 
Result so far: 179.0
The remainder is 261 after subtracting 8289 from 8550.
Grab the next digit (6) from the dividend, add it to 261, then carry on: 2616 / 921

Advancing to step 7:
921 goes into 2616 2 times with a remainder of 774.
Use 2 as the next digit of our solution. 
Result so far: 1792.0
The remainder is 774 after subtracting 1842 from 2616.
Take the next digit (4) from the dividend and append it to 774, then repeat: 7744 / 921

Moving on to step 8:
921 can be fit into 7744 8 times, resulting in a remainder of 376.
The next digit of our result is 8. 
Result so far: 17928.0
Subtract 7368 from 7744 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 9:
3760 divided by 921 is 4 with a remainder of 76.
The next digit of our result is 4. 
Result so far: 17928.4
If we subtract 3684 from 3760, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 10:
When dividing 760 by 921, we get 0 with a remainder of 760.
The number 0 becomes the next digit in our result. 
Result so far: 17928.4
Subtracting 0 from 760 leaves us with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Step 11:
7600 divided by 921 is 8 with a remainder of 232.
The number 8 becomes the next digit in our result. 
Result so far: 17928.408
The remainder is 232 after subtracting 7368 from 7600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 12:
When dividing 2320 by 921, we get 2 with a remainder of 478.
Put 2 as the next digit of the answer. 
Result so far: 17928.4082
If we subtract 1842 from 2320, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Let's proceed to step 13:
921 goes into 4780 5 times with a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 17928.40825
Subtracting 4605 from 4780 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 14:
When dividing 1750 by 921, we get 1 with a remainder of 829.
Put 1 as the next digit of the answer. 
Result so far: 17928.408251
If we subtract 921 from 1750, we get 829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8290, and continue the process.

Moving on to step 15:
The number 921 fits into 8290 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 17928.4082519
Subtract 8289 from 8290 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 16:
The number 921 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 17928.4082519
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 17928.4082519, and the remainder is 1e-08.
